“…At least in the Triatominae, these pores are known to be associated with glandular units (Weirauch,2008), and we propose that the pores in Agriocleptes may also represent the openings of glandular units. Given that the pores are sexually dimorphic in Agriocleptes , we propose that they are likely involved in male‐specific behaviors, and we speculate that they might produce pheromones as is the case with other sexually dimorphic structures in Heteroptera (Lawrence and Staddon,1975; Weirauch,2003,2004; Pluot‐Sigwalt,2008).…”

Apiomerini (Reduviidae: Harpactorinae) collect plant resins with their forelegs and use these sticky substances for prey capture or maternal care. These behaviors have not been described in detail and morphological structures involved in resin gathering, transfer, and storage remain virtually undocumented. We here describe these behaviors in Apiomerus flaviventris and document the involved structures. To place them in a comparative context, we describe and document leg and abdominal structures in 14 additional species of Apiomerini that represent all but one of the 12 recent genera in the tribe. Based on these morphological data in combination with the behavioral observations on A. flaviventris, we infer behavioral and functional hypotheses for the remaining genera within the tribe Apiomerini. Setal abdominal patches for resin storage are associated with maternal care so far only documented for species of Apiomerus. Based on the occurrence of these patches in several other genera, we propose that maternal care is widespread within the tribe. Ventral abdominal glands are widespread within female Apiomerini. We propose that their products may prevent hardening of stored resins thus providing long-term supply for egg coating. Judging from the diverse setal types and arrangements on the front legs, we predict six different behavioral patterns of resin gathering within the tribe.

“…Reduviidae have glands that release compounds associated with defensive behavior, alarm, and mating (Weirauch 2003(Weirauch , 2004(Weirauch , 2006bVitta et al 2009). However, the current study is the Þrst record of a glandular epidermis associated with wax secretion in Reduviidae, which calls for further studies to explain the physiological or ecological functions of the wax released onto the body surface during speciÞc developmental stage of H. angulosus.…”

Beginning at the third instar, the generalist predator Harpactor angulosus (Lepeletier & Serville) (Reduviidae: Harpactorinae) appears gray in color because of the presence of a whitish particulate wax-like material covering all body segments. In this study, we tested the hypothesis that epidermal cells are responsible for the secretion of the wax-like substance onto the cuticle of H. angulosus. The integument of third instar to the adults of H. angulosus have no external structures specialized in wax secretion, as the wax particles are deposited in a filamentous manner. Third to fourth instars and adult stages have a single-layered epidermis composed of columnar cells. In contrast, lack of wax deposit on the body surface of first and second instars is associated with flattened epidermal cells. The columnar epidermal cells are characterized by a well-developed nucleus, basal cell surface with large infoldings, and a cytoplasm rich in vacuoles. These vacuoles are negative for the presence of carbohydrates and proteins, but strongly positive for the presence of lipids. The structural features of the epidermis and the presence of lipid droplets suggest that lipid metabolism is active within the epidermis from the third instar to the adult of H. angulosus. This is the first record of a glandular epidermis associated with wax secretions in Reduviidae.

“…Since this publication, knowledge about cimicomorphan morphology has increased for many families. Schuh and Slater ( 1995 ) made important new observations about the Cimicomorpha morphology; other important contributors to the morphology of the infraorder are Weirauch ( 2003Weirauch ( , 2005Weirauch ( , 2006, Schuh ( 2006 ), Popov ( 2008 ), and Cassis et al ( 1999 ). Tian et al ( 2008 ) analyzed the phylogenetic relationships of 12 cimicomorphan families based on molecular dataset and different methods of phylogenetic reconstruction, fi nding small differences from Schuh and Štys ( 1991 ), but did not propose taxonomic changes.…”

A review of Heteroptera classifi cation, biogeography, and phylogeography is presented. The use of molecular data signifi cantly expanded the knowledge of phylogenetic relationships among and within heteropteran infraorders. However, taxa historically less studied continue to receive little attention. Promising, new molecular approaches with increased genetic markers and broader taxon sampling, as well as new morphological approaches (e.g., microtomography), are the future for more stable classifi cations and a better comprehension of the heteropteran evolutionary history, but their application is still incipient. A non-exhaustive overview of studies about Neotropical heteropteran biogeography is made and discussed, including those about intercontinental connections and regional distribution patterns. The most comprehensible studies, and more promising area, seem to be those focused on distribution patterns, especially employing macroecological methods, and trying to elucidate what are the major factors responsible for the distribution of the group in the Neotropics. Finally, we present an overview of phylogeographic studies involving Neotropical Heteroptera. It is clear that the best biogeographic and phylogeographic studied groups are those with medical and economical importance (e.g., Reduviidae and Pentatomidae).
